ADJUSTABLE SLIDING AND SWINGING WINDOW-SASH.

SPECIFICATION forming part of Letters Patent No. 569,146, dated October6, 1896. Application filed January 27, 1896. Serial No- 576,932. (Nomodel.)

To all whom it may concern.-

Be it known that I, EDWARD S. BARNEY, a

citizen of the United States, residing in the city and county of SanFrancisco, State of California, have invented an Improvement inAdjustable Sliding and Swinging Window- Sashes; and I hereby declare thefollowing to be a full, clear, and exact description of the same.

My invention relates to that class of sashes which are adapted toordinarily slide in vertical guides in the casing, and which are alsoadapted to be hinged so as to be temporarily opened inwardly from thecasing about the hinges for the purpose of obtaining access to bothsides of the window. 1

It consists, essentially, in a novel device to which the cord isattached and which is so constructed as to be detachably connected withthe sash.

It also consists in details of construction which willbe more fullyexplained by reference to the accompanying drawings, in which Figure 1is a view of a sash, showing the cord-retainer connected with it. Fig. 2shows the short form of retainer, the movable stop, and the sash-latchdisengaged. Fig. 3 is a perspective view of the cord-retainer. Fig. 4 isa detached view of the stop.

A is the sash, which is adapted to slide in grooves or channels in thecasing B, and O are hinges of any suitable or desired description bywhich one side of the sash may be temporarily connected with the casing,so that when the stop has been removed from the other side the sash canbe swung inwardly about the hinges. In order to allow the sash to thusswing, it is necessary to disengage the cord of the balance-weight, andin order to do this conveniently and to engage the cords with the sashand lock them in engagement when the sash is in position to slide in thecasing I employ the following device:

D is the cord-retainer, which is adapted to hold the window cord, band,or other fastening. This retainer consists of a semitubular piece E,having an interior diameter sufficient to allow thecord to fit easilywithin it, and the exterior surface is fitted to lie in a groove orchannel in the edge of the sash, or,

if preferred, it may be reversed and its convex surface allowed to slidein a correspondingly-shaped groove in the casing, in which case the edgeof the sash would not need to be grooved. This retainer may be madesemicylindrical or polygonal, as desired, and

it has a portion E, shown in the present case near the lower end, madecompletely cylindrical or bent around so as to form an engagement forthe knot or enlargement in the end of the cord, which is thus secured tothe cordretainer. The cord passes from this point up over a pulley inthe usual manner and thence extends down to the weight which serves tocounterbalance the sash. Near the bottom of the retainer a hole or slotis made,

as shown at F, and a pin or bolt G is slidable transversely through thesash, so that its point will engage the slot in the cord-retainer whenthe two are brought into line, and thus lock it to the sash. When thetwo-are thus engaged,

it will be seen that the weight upon the cord will act to counterbalancethe sash, the cordretainer moving with the sash as the latter slides upor down. In order to make this engagement automatic, the end of thesliding bolt is beveled upon the upper side, so that when thecord-retainer is held stationary at any point the sash is engaged withit by sim- 8o ply sliding it up until the beveled point of the boltdrops into the slot in the cord-retainer, a spring acting to press thebolt forward. Then when the sash is again drawn down, the cordretainerwill move with it and thereafter form 8 5 a part of the movingstructure. The inner end of the bolt has a suitable head by which it canbe withdrawn when the parts are in position to disengage.

The sliding bolt has a notch G formed upon the lower side at such apoint that when the bolt has entered the slot in the cord-retainer thisnotch will engage the edge of the slot, and as long as the weight actsto pull the cord retainer and sash upwardly this 5 notch will remainlocked with the edge of the slot and it will be impossible to withdrawthe bolt. This prevents the weight from being disengaged whenthe sash isdown and thus prevents the weight from dropping violently too andcausing injury.

WVhen it is desired to disengage the cordretainer from the sash, it isdone by pushing the sash up to the top of its travel. This brings theupper end of the cord-retainer into contact with a stop, as shown at H,which prevents its moving any farther. This contact takes place justbefore the sash has reached the highest point to which it can be moved,and a little farther movement of the sash lifts the locking pin or boltenough to disengage the transverse notch from the edge of the slot. Thebolt may then be withdrawn by pulling it backward through the sash untilit is released from the cord-retainer. The sash is then slid downapproximately to the bottom of its travel, when it will be clear of thecord-retainer, and the hinges upon the opposite side being properlyengaged the stop in the sash can be removed and the sash swung about itshinges for any purpose desired. When the sash is again closed into itsplace in the casing,it is moved upward until the sliding sash-bolt Greaches the bottom of the cordretainer, when it will be pressed inwardlyby reason of the beveled upper side of its inner end, and when itreaches the slot in the retainer it will be immediately forced into itautomatically by the action of the spring. The transverse notch engagingthe edge of the slot will lock the two together as soon as the sash isdrawn down so that the weight is again caused to pull upwardly upon theretainer, and the two will remain thus locked together without anydanger of disengagement until the sash is again pushed to its highestpoint.

In some cases the cord-retainer is made short, as shown in Fig. 2, and aremovable stop H is employed to arrest and hold it without allowing theretainer to slide to the top of the window. This stop H has the outerend bent into a semicircular form, so that it will slip over the cord,and it has an extension which is adapted to fit into a slot or openingor be otherwise attached to the windowcasing. This device being thusattached, the

curved portion will clasp the window-cord above the cord-retainer andthe latter will be arrested and held by the stop wherever it may beinserted. The retainer may then be disengaged from the sash, aspreviously described, leaving the sash free to be turned upon itshinges.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with a window-sash, of a cord-retainer verticallyslidable between the sash and the casing, said retainer having a slot orcatch and a bevel-pointed latch slidable through the sash at rightangles with its line of travel, and adapted to automatically engage theretainer when in line with the slot.

2. The combination with a window-sash and a hinge about which it isturnable out of its line of travel, of a cord-retainer verticallyslidable between the edge of the sash and the casing, having a slot, atransversely-slidable spring-actuated bolt upon the sash, the point ofwhich is formed to automatically engage the cord-retainer, and alocking-notch on the bolt to prevent its being withdrawn until the Vsash is relieved of the pull of the weights.

3. The combination with a window-sash, of

a cord-retainer vertically slidable between' the edge of the sash andthe casing having its upper end adapted to contact with a stop on thecasing when the sash is at the top of its vertical travel, whereby thesash is relieved of the pull of the weights, a transverselysliding boltmovable on the sash with its point adapted to automatically engage aslot in the cord-retainer when in line therewith, and a notch in thebolt which locks it in engagement with the retainer, and prevents itswithdrawal until the retainer contacts with the stop and allows the sashto move upward enough to disengage the lock.

4. The combination, with a window-sash, a cord-retainer verticallyslidable between the sash and the casing and means for engaging Inwitness whereof I have hereunto set my hand.
